Retinal Pathology and Synucleinopathy in the Visual Pathway of α‐Synuclein Preformed Fibril Mouse Model of Parkinson's Disease

Brain and Behavior, Volume 16, Issue 5, May 2026.
Schematic summary of visual electrophysiology and retinal and brain pathology. The diagram integrates PVEP abnormalities, retinal pathology, and brain pathology in PFF‐injected mice. Based on behavioral outcomes, the three groups were categorized as control, prodromal PD, and PD, corresponding to the PBS, 3‐month PFF (3 MPI), and 6‐month PFF (6 MPI ...

DUSP1 Attenuates Renal Injury in Diabetic Nephropathy by Modulating Ferroptosis: Evidence From Animal Experiments

Immunity, Inflammation and Disease, Volume 14, Issue 2, February 2026.
ABSTRACT Objective Emerging evidence suggests that ferroptosis contributes significantly to the progression of diabetic nephropathy (DN). This study aimed to explore the potential association between dual specificity phosphatase 1 (DUSP1) and ferroptosis in a streptozotocin‐induced DN rat model.

Corneal Densitometry Changes after Epithelium-Off Corneal Collagen Crosslinking

QJM: An International Journal of Medicine, 2021
Abstract Background Keratoconus is a progressive non-inflammatory, degenerative disease that affects the integrity of the collagen matrix within the corneal stroma. Corneal cross-linking (CXL) has been described as the only modality in halting the disease progression over the past decade.
